Activating 02 Discount for Teachers

[sophwick]

I'm trying to buy a phone and contract with 02 for the first time and I am eligible for the 02 25% teacher discount however I can't seem to access this online. I've followed all the advice on the forums and used the code TEACH at checkout but it tells me this is invalid. How can I access this with the shops closed?

Thanks

When it comes to the reason you are calling stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.
Say "Upgrade", "Lost/Stolen" or "Fraud" if you have to, to get put through to someone.
8.00am is the best time to call if you can.
